When I upload my code from Perforce to Code Collaborator the client tool allows me to "Create New Review" or "Add to Existing Review". "Add to Existing Review" pulls back all open reviews, including ...
This can be particularly annoying for users who are administrators and also create reviews. In this case it takes a long time to load the "Add to Existing Review" list in the Client GUI because these users have access to every open review (or at least by default).
